Pehr Magnus Arvid Säve (19 April 1811 – 10 November 1887)[1] was a Swedish teacher, cultural historian and artist.

[2] Säve started out as a teacher in Visby 1835–57,[3] and he soon became a pioneer for the Gotlandic cultural history.

[4] On the behalf of the Royal Swedish Academy of Letters, History and Antiquities he collected facts about Gotland's heritage, language, geography and culture.

His notes are collected in six large volumes in Uppsala University Library.

[6] He also gathered and wrote down Gotlandic traditional tales, which he called sagas.
